Some 32 plants on which eggs have been found, or upon which moths 
have been observed to oviposit, are included in this list. A number 
of these are present as weeds in corn and cotton fields and the eggs 
deposited are more likely laid on account of proximity than otherwise. 
In the case of the wild-onion flowers and rosebuds it is probable that 
the scarcity of food at such times (April and October) attracts them to 
these plants. Indeed, roses in gardens and cemeteries seem to be the ' 
first plants chosen for oviposition early in the spring. Oviposition on 
alfalfa, tobacco, etc., is by no means accidental, as the larv^ thrive 
well on these plants. The number of miscellaneous plants is sufficient 
to show, however, that under certain conditions no ver}^ careful selec- 
tion is exercised by the female in ovipositing. 
It must be mentioned that garden vegetables were at all times very 
free from bollworm eggs, especially in the spring and fall. This is at • 
variance with the records of a number of observers, who have found 
larvae common on such plants. 
The occurrence of larvae on miscellaneous plants will be considered 
on a later page. 
XUMBEE OF EGGS LAID BY A SIXGLE MOTH. 
Numerous moths were kept under observation at various times 
during the season to determine the number of eggs which would be 
deposited under different conditions. 
Observations on early spring moths in the northern part of Texas 
seem to indicate that the number of eggs laid b}^ them is rather small, 
averaging only ttlo for each moth of a series of ten which were kept in 
the laboratory. At Victoria, however, in the southern part of the 
State, moths developing from overwintered pupte averaged over 1,200 
each for a series of five moths.

General average for each moth, 1,098. __ 
It will be noticed that there is nearly always a gradual decline in 
the number of eggs laid during each succeeding da}". In the case of 
a few moths, more than one day shows a considerablv greater oviposi- 
tion than the others, the number of eggs rising to one maximum, 
decreasing, and then rising again, thus resulting in an irregular curve,
